I find almost all talk here point in a negative way.
That is because if you are well prepared, it is not too difficult to pass the first one, that makes to whole thest a bit senseless.
At the end your flying skills and your experience do not count very much its all down to the DLR Assessment and compared to other assessments, like easyjet or others, the DLR is not quite a good one and you do not get a real feedback at the end like easyjet does.
And it is not really true that they couldnt find enough italian pilots, as Greenpilots says, it was simply the case that most of the applicants (italian or not) have been selected out on the SIM by LH guys. Screening has been stopped after that.
Now after the case has been solved and there is an agreement with the LH pilots, the screening has started again and most of the italian pilots are beeing called again.
So in your case, get prepared, I guess the sky test will make it, if you pass the fist stage in Hamburg, take some hours on a 737 SIM if you are not current on it. If you pass the SIM then get prepared for the assessment.
Good luck.
